Hi. I'm a new one here.
About the Fokker G-1A and -1B. Originally coming from the Netherlands, I can
tell you there NEVER were such designations!
Most considering W. Green the best informed writer, I'll tell you he was completely off on this! The Fokker distinction was Fokker G-1 (Mercury) and
Fokker G-1 (Wasp) referring to the engines fitted. So throw away the "G-1A" and "G-1B" nomenclature!
